Install using the Makefile:
$ sudo make install
install -m 0644 "nfs-client-ping-mount.service" "/etc/systemd/system/nfs-client-ping-mount.service"
install -m 0755 "nfs-client-ping-mount.sh" "/usr/local/bin/nfs-client-ping-mount.sh"
systemctl daemon-reload
systemctl enable nfs-client-ping-mount.service
systemctl start nfs-client-ping-mount.service
Simply add your NFS filesystem mounts to /etc/fstab as you would normally.
Optionally add the noauto argument to the fs_mntops field.
